Former India all-rounder Yuvraj Singh's father, Yograj Singh, opined that India's young cricketers, which includes Vaibhav Suryavanshi, must focus on improving their fitness to play all three formats. "My vision is Test cricket. Can you survive five days? That's the real test," he said. He added that players struggle nowadays because they're only concentrating on T20, IPL and 50 overs.
